Missed Oppourtunity for Google Buzz?

Did you notice anything strange about Google Buzz or was it just me? No, I’m not talking about the questionable privacy issue, that’s been resolved…and rather quickly I might add (Yah, I’m a Google fanboy).

Google Buzz has no advertisements.

So did Google miss an opportunity to place more ads? Are they waiting for something? In case you’re wondering, Google generates nearly all of it’s revenue from advertisements, yet Google Buzz doesn’t have advertisements. I suppose it isn’t so strange…Calendar and Docs are missing advertisements as well. Anyone have any ideas on how Google determines where to place ads?
